Effects of chronic fluorosis on the brain.
Highlights Reviewing the mechanism of brain injury caused by chronic fluorosis is of great significance for protecting residents in fluorosis endemic areas. Abstract This article reviews the effects of chronic fluorosis on the brain and possible mechanisms. We used PubMed, Medline and Cochraine databases to collect data on fluorosis, brain injury,

Public-health risks from tea drinking: Fluoride exposure.
Aims: Due to new evidence on fluoride neurotoxicity during early life, this study examined maternal exposure to fluoride through tea consumption in a low-fluoride region and measured fluoride releases from commercially available teas (tea bags and loose teas) to determine the need to limit fluoride exposure. Methods:
-
Decreased learning ability and low hippocampus glutamate in offspring rats exposed to fluoride and lead.
Fluoride (F) and lead (Pb) are two common environmental pollutants which are linked to the lowered intelligence, especially for children. Glutamate, a major excitatory neurotransmitter in the central nervous system, plays an important role in the process of learning and memory. However, the impact of F and Pb alone or

Studies on alterations in brain lipid metabolism following experimental fluorosis
The neurotoxic effect of fluoride on lipid content of brain was assessed in rabbits during experimental fluorosis. Sodium fluoride at 5, 10, 20 and 50 mg/kg body weight/day was injected subcutaneously for 100 days into 60 rabbits of both sexes. The control animals were given 1 cc distilled water/kg body

Histopathological investigation of fluoride-induced neurotoxicity in rabbits.
SUMMARY: Brain tissues for neurohistopathological study were obtained at autopsy from albino rabbits that had been subcutaneously injected for 15 weeks with 0, 5, 10, 20, and 50 mg of sodium fluoride in 1 mL of aqueous solu- tions/kg bw/day. Neuropathological changes occurred with loss of the mo- lecular layer and glial cell layer

Fluoride's Direct Effects on Brain: Animal Studies
The possibility that fluoride ingestion may impair intelligence and other indices of neurological function is supported by a vast body of animal research, including over 40 studies that have investigated fluoride's effects on brain quality in animals. As discussed by the National Research Council, the studies have consistently demonstrated that fluoride, at widely varying concentrations, is toxic to the brain.

Fluoride Affects Learning & Memory in Animals
An association between elevated fluoride exposure and reduced intelligence has now been observed in 65 IQ studies. Although a link between fluoride and intelligence might initially seem surprising or random, it is actually consistent with a large body of animal research. This animal research includes the following 45 studies (out

Fluoride & IQ: 76 Studies
Note: See the Updated list of fluoride IQ studies at https://fluoridealert.org/researchers/fluoride-iq-studies/the-fluoride-iq-studies/ • As of July 18, 2022, a total of 85 human studies have investigated the relationship between fluoride and human intelligence. • Of these investigations, 76 studies have reported that elevated fluoride exposure is associated with reduced IQ in humans. • The studies

Fluoride: Developmental Neurotoxicity.
Developmental Neurotoxicity There has been a tremendous amount of research done on the association of exposure to fluoride with developmental neurotoxicity. There are over 60 studies reporting reduced IQ in children and several on the impaired learning/memory in animals. And there are studies which link fluoride to Attention Deficit Hyperactivity Disorder. Teaching
